IMPROVEMENTIN STILLS FOR HYDROCARBONS.

The Schedule referred to in these Letters Patent and making part of the name To all 'whom 'it may conce-r11.

Be it known that we, SAMUEL A. HILL and CHARLES F. THUMM, of Oil City, in the county of Venango and State of ulennsylvania, have inventeda new and useful Improvement in Stills for Hydrocarbons; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings andto the letters of reference marked thereon.

The nature of our invention consists in connecting together a series of stills, and providing the bottoms of said stills with Ways or channels so arranged that the hydrocarbon will iiow in a zig-zag current and thin sheet over the bottom of each still for the purpose of a continuous distillation of hydrocarbons.

.lo enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

In `the accompanying drawings which form part of our speeication- Figure 1 is a perspective view of our improvement in stills for hydrocarbon.

Figureis'aongitudinal and transverse section of the same cut through at line y of iig. 1.

In the drawings- A B Cj represent the stills, which are provided with suitable furnaces m, and goose-necks e f g, each of which should be attached to a suitable condenser.

l represents mm1-holes," which are used forcleaning out the stills.,

h i are pipes which connect the stills together.

k represents the pipe used for conveying the hydrocarbon to the stills.

J is a pipe used for the purpose of drawing o the,

tarry mattei' known as residuum or the refuse of distillation.

S represents plates which are secured on their Iedge to the' bottornof the still, and are used for forming the zig-zag ways or channels through which the hydro.- carbon flows.

As the construction of our improvement in stills will be readily understood from the foregoing description and by reference to the accompanying drawings, we -will therefore proceed to describe the operation of our invention. v

The crude oil enters the still C through the pipe 7c, (fire being made in the furnaces m,) as the oil iiows over the bottom of the stills, (as indicated by the arrows,) the light portion of the oil is evolved in still O, and the unevolved portion ows through the pipe h into still B, where another portion is evolved, and the unevolved portion passes through pipe t' into still A, where another portion is evolved, after which the res'iduum is drawn oiI" at pipe J. By this arrangementI of stills for hydrocarbons a uniform specific gravityf and iire test may always be obtained for burning oils. Q Having thus described the nature, construction, and operation of our improvement,

What we claim as of our invention is A series of stills connected'together by pipes which connect with zig-zag ways or channels made in or on the bottom of each still, each still of the series being provided with a goose-neck and condenser, as herein described.
